The answer does not work for me(sdk 21, samsung galaxy s5). After searching and testing, I find that the key point for setting a dialog for fullscreen is the false in your dialog style. Most styles of Dialog in sdk set it true! Set it false in a style and use it in

AlertDialog.Builder = new AlertDialog.Builder(getActivity(), R.style.YourStyle);

your style may look like

after setting it false, it should be fullscreen. And more, you can use

dialog.getWindow.setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.WRAP_CONTENT);

to set it's height to wrap_content. Hope to help someone.
